Abstract

La présente invention concerne des nanoparticules d'acide silicique stabilisées à l'hydronium, la formulation obtenue à partir de ladite suspension diluée, la poudre obtenue à partir de ladite suspension déshydratée et la préparation ou la forme galénique obtenue à partir de ladite suspension, formulation ou poudre, leur préparation et leur utilisation dans toutes sortes d'applications dans les domaines de l'alimentation, de la médecine, des produits pharmaceutiques ou cosmétiques. La présente invention propose une suspension stable de nanoparticules d'acide silicique colloïdales ayant un pH inférieur à 0,9, une concentration molaire de silicium comprise entre 0,035 et 0,65, une concentration en eau libre d'au moins 30 % (p/v) et un rapport entre les ions hydronium et les concentrations molaires de Si supérieur à 2 et de préférence inférieur à 4. La présente invention propose en outre un procédé de préparation d'une suspension stable de nanoparticules d'acide silicique colloïdales qui comprend les étapes consistant à fournir une solution aqueuse de silicium inorganique ou organique et à mélanger rapidement ladite solution aqueuse de silicium inorganique ou organique avec de l'eau contenant un composé acide puissant à une température inférieure à 300° C, de préférence comprise entre 1 et 25 °C, pour former une suspension de nanoparticules d'acide silicique colloïdales ayant un pH inférieur à 0,9, stabilisée par des ions hydronium, le rapport entre les ions hydronium et les concentrations molaires de Si étant supérieur à 2 et de préférence inférieur à 4, pour une concentration molaire de silicium comprise entre 0,035 et 0,65 et une concentration en eau libre d'au moins 30 % (p/v).
